Struct std::num::NonZeroU128
1.28.0 · source · [−]#[repr(transparent)]pub struct NonZeroU128(_);
Expand description
An integer that is known not to equal zero.
This enables some memory layout optimization.
For example, Option<NonZeroU128>
is the same size as u128
:
use std::mem::size_of;
assert_eq!(size_of::<Option<core::num::NonZeroU128>>(), size_of::<u128>());

impl NonZeroU128
const: 1.28.0 · sourcepub const unsafe fn new_unchecked(n: u128) -> NonZeroU128
pub const unsafe fn new_unchecked(n: u128) -> NonZeroU128
Creates a non-zero without checking whether the value is non-zero. This results in undefined behaviour if the value is zero.
Safety
The value must not be zero.
const: 1.47.0 · sourcepub const fn new(n: u128) -> Option<NonZeroU128>
pub const fn new(n: u128) -> Option<NonZeroU128>
Creates a non-zero if the given value is not zero.

1.53.0 (const: 1.53.0) · sourcepub const fn leading_zeros(self) -> u32
pub const fn leading_zeros(self) -> u32
Returns the number of leading zeros in the binary representation of self
.
On many architectures, this function can perform better than leading_zeros()
on the underlying integer type, as special handling of zero can be avoided.
Examples
Basic usage:
let n = std::num::NonZeroU128::new(u128::MAX).unwrap();
assert_eq!(n.leading_zeros(), 0);
Run1.53.0 (const: 1.53.0) · sourcepub const fn trailing_zeros(self) -> u32
pub const fn trailing_zeros(self) -> u32
Returns the number of trailing zeros in the binary representation
of self
.
On many architectures, this function can perform better than trailing_zeros()
on the underlying integer type, as special handling of zero can be avoided.
Examples
Basic usage:
let n = std::num::NonZeroU128::new(0b0101000).unwrap();
assert_eq!(n.trailing_zeros(), 3);

sourcepub const fn checked_add(self, other: u128) -> Option<NonZeroU128>
pub const fn checked_add(self, other: u128) -> Option<NonZeroU128>
Add an unsigned integer to a non-zero value.
Check for overflow and return None
on overflow
As a consequence, the result cannot wrap to zero.
Examples
#![feature(nonzero_ops)]
let one = NonZeroU128::new(1)?;
let two = NonZeroU128::new(2)?;
let max = NonZeroU128::new(u128::MAX)?;
assert_eq!(Some(two), one.checked_add(1));

sourcepub const unsafe fn unchecked_add(self, other: u128) -> NonZeroU128
pub const unsafe fn unchecked_add(self, other: u128) -> NonZeroU128
Add an unsigned integer to a non-zero value,
assuming overflow cannot occur.
Overflow is unchecked, and it is undefined behaviour to overflow
even if the result would wrap to a non-zero value.
The behaviour is undefined as soon as
self + rhs > u128::MAX
.
Examples
#![feature(nonzero_ops)]
let one = NonZeroU128::new(1)?;
let two = NonZeroU128::new(2)?;
assert_eq!(two, unsafe { one.unchecked_add(1) });
Runsourcepub const fn checked_next_power_of_two(self) -> Option<NonZeroU128>
pub const fn checked_next_power_of_two(self) -> Option<NonZeroU128>
Returns the smallest power of two greater than or equal to n.
Check for overflow and return None
if the next power of two is greater than the type’s maximum value.
As a consequence, the result cannot wrap to zero.
Examples
#![feature(nonzero_ops)]
let two = NonZeroU128::new(2)?;
let three = NonZeroU128::new(3)?;
let four = NonZeroU128::new(4)?;
let max = NonZeroU128::new(u128::MAX)?;

assert_eq!(None, max.checked_next_power_of_two() );
Runsourcepub const fn log2(self) -> u32
pub const fn log2(self) -> u32
Returns the base 2 logarithm of the number, rounded down.
This is the same operation as
u128::log2
,
except that it has no failure cases to worry about
since this value can never be zero.
Examples
#![feature(int_log)]
assert_eq!(NonZeroU128::new(7).unwrap().log2(), 2);
assert_eq!(NonZeroU128::new(8).unwrap().log2(), 3);
assert_eq!(NonZeroU128::new(9).unwrap().log2(), 3);
Runsourcepub const fn log10(self) -> u32

Returns the base 10 logarithm of the number, rounded down.
This is the same operation as
u128::log10
,
except that it has no failure cases to worry about
since this value can never be zero.
Examples
#![feature(int_log)]
assert_eq!(NonZeroU128::new(99).unwrap().log10(), 1);
assert_eq!(NonZeroU128::new(100).unwrap().log10(), 2);

Multiply two non-zero integers together.
Check for overflow and return None
on overflow.
As a consequence, the result cannot wrap to zero.
Examples
